Explanation:

Answer: Catalyst. Any molecule that will increase the rate of a chemical reaction, does not participate directly in the reaction and therefore is reusable, and does not supply the energy for the reaction (heat or ATP does). Enzymes work on one reactant, called a. Substrate.

"Enzymes are organic catalysts" refers to the fact that enzymes are an organic class of biological molecule that act as catalysts in chemical reactions.

Catalysts are compounds that speed up chemical reactions without being consumed or changed in any way. In living organisms, enzymes are essential for many biochemical processes, including the breakdown of food during digestion, the synthesis of molecules, and the facilitation of cellular processes. Enzymes help maintain vital biochemical processes, maintaining the fundamental activities of life, by reducing the activation energy required for a reaction.

Answer:

Natural Earth cycles result in increased temperatures    

Explanation:

By temperature looking te the graph we can see that there is a soft increase in temperature from 1880- 1940. It seems that from 1940-1980, the temperature was stable, but since 1980 there is a noticeable temperature increase, until the year 2000. By year there are increases and decreases in temperature, which correspond to the different seasons and temperature cycles over the year, but in a general vision, the temperature is obviously increasing with the pass of years.

According to the statement, the spring growing season is becoming longer than in the second half of the 20th century, and it is coming earlier. This is reflected in the graph from the year 1980 to 2000.

According to the graph and the statement, we could estimate what is going to happen in the next years is there is no change. Although, we can not predict it for sure.

C - Organic Molecules. Most carbon-based molecules are called organica molecules.

A is wrong because inorganic molecules are non-carbon-based, and carbon based molecules are not ions, so B is wrong too. D is wrong because macromolecules is does have carbon, as every living thing, but macromolecules is not another name for carbon based molecules, Therefore organic molecules is the answer.

The difference between past time focus and present time focus is that present time focus refers to the moment we are living in, the moment we are going to now. The past focus is that we are paying attention to the things that we have experienced in the past. The basic difference is one things is about being focused on the present situation while the other is thinking about past situations or experiences.

Answer:

the answer is option c cellulose..

Explanation:

Cellulose is a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre.

Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as energy storage

Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body.

hope it helped you and the answer is correct

The term that is used for structure and not for energy is cellulose, which is difficult to break apart. The correct option is c.

A molecule called cellulose is made up of hundreds, and occasionally even thousands, of carbon, hydrogen, and oxygen atoms. The primary component of plant cell walls, cellulose, keeps plants rigid and upright.

A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. Most green plants synthesize this polysaccharide as a form of energy storage.

Animals, fungi, and bacteria all use the multibranched polysaccharide of glucose known as glycogen to store energy. The primary form of glucose storage in the body is represented by the polysaccharide structure.

Therefore, the correct option is C) cellulose, which is difficult to break apart.

Answer:

no shape of molecules doesn't affect the chemical bond

Answer:

There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour should lie for the strength of bonding to be maximized. In contrast, in a covalently bonded compound, the atoms adopt specific locations relative to one another, as in the tetrahedral arrangement of hydrogen atoms around the central carbon atom in methane, CH4, or the angular arrangement of atoms in H2O.

The correct answer is C) Genetic influences exert a larger role in Type II diabetes than in Type I diabetes.

Explanation:

Monozygotic or identical twins share the same genes; due to this, if twins have the same diseases or there are concordance rates, it can be concluded the disease or condition is influenced by genetics.

In the case of diabetes, the concordance rate for Type II diabetes was high (80%), which proves this type of diabetes is influenced to a large extend by genetics. Similarly, in Type I diabetes genetics seem to have an influence but this is not as strong as in Type II because the rates were lower (30-50%).

Moreover, the results of dizygotic twins (twins with different genes) show diabetes is influenced by genetics because in these twins the genetics are not the same, and therefore the concordance rate is low.

Answer:

114 gram of salt is required.

Explanation:

Below are the following given data in the question:

Prepared salinity water = 30 ppt

Weight of salt used = 3.26 kg

The volume of water = 114 L

Below is the calculation.

4000 mL = 4000/1000 = 4L

Let the used = x kg

3.26/114 = x/4L

Now solve for the x.

x = 0.114 kg or 114 gram

The answer is b

Explanation:

Answer:All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.

Explanation:

To determine if something is made out of cells, several approaches can be employed, including microscopic and biochemical assays for physical and chemical assessments.

Visual inspection using a microscope can reveal the presence of cell-like structures, such as membranes, nuclei, or organelles. Staining techniques, such as fluorescent dyes or immunohistochemistry, can further enhance the visibility of cellular components.

DNA analysis can also be conducted by extracting genetic material from the sample and performing sequencing or polymerase chain reaction (PCR) to detect DNA specific to cells.

Biochemical assays can be used to identify cellular components, such as proteins or enzymes, which are characteristic of cell composition.

probably A, B, or D.

Explanation:

Answer:

14. A Carbon dioxide

15. C glucose

Explanation:

#14 is A, carbon dioxide because cellular respiration releases Carbon dioxide (co2) and H20 (water).

#15 is C, glucose  because photosynthesis takes in Co2, h20, and Sunlight and creates sugar (glucose) and oxygen.

The products of photosynthesis are the reactants of cellular respiration and vice versa.
